Reports Conference Reports Nsdi '14: 11th Usenix Symposium on Networked Systems Design and Implementation Opening Remarks

ion (with a SQL-like language) is too high-level; how would languages like Erlang fit into this project? In fact, the authors really thought about using a functional language instead of a custom DSL. Someone asked whether they could still run into inconsistencies between layers. Tim replied that they don’t allow state to expire due to lack of use. They are adding the ability to have timeout events for removing rules. Aditya Akella (University of Wisconsin–Madison) asked about how the compiler works and whether it can handle all types of consistency semantics. Tim replied that Flowlog supports some things that OpenFlow does not. When their compiler detects forwarding rules, it produces netcore code and uses the netcore compiler. Andrew Ferguson (another author) pointed out that some parts of the policy might be directed toward a single switch, and that that is an abstraction introduced by netcore.
